24. Mention what is the difference between elasticity and scalability in cloud computing?

Scalability in the cloud is the way in which you increase the ability to service additional workloads either by adding new servers or accommodating them within the existing servers. Elasticity is the process by which you can either add or remove virtual machines depending on the requirement in order to avoid wastage of resources and reduce costs.

25. What are the service accounts? How will you create one?

This is one of the most common Google Cloud interview questions. Service accounts are the special accounts related to a project. They are used for the authorization of Google Compute Engine in order to be able to perform on behalf of the user thus receiving access to non-sensitive data.

There are different service accounts offered by Google but mainly, users prefer to use Google Cloud Platform Console and Google Compute Engine service accounts.

The user doesn’t need to create a service account manually. It is automatically created by the Compute Engine whenever a new instance is created. Google Compute Engine also specifies the scope of the service account for that particular instance when it is created.

26. What are projects in the context of Google Cloud?

Projects are the containers that organize all the Google Compute resources. They comprise the world of compartments and are not meant for resource sharing. Projects may have different users and owners.

27. Suppose you have deleted your instance by mistake. Will you be able to retrieve it back? If yes, how?

While It is a very simple question, it is based on a deep understanding of the Google cloud platform. The answer is no. It is not possible to retrieve the instances that have been deleted once. However, if it has been stopped, it can be retrieved by simply starting it again.

28. What is Google BigQuery? What are the benefits of BigQuery for data warehouse practitioners?

Google BigQuery is used as a data warehouse and stores all the analytical data in an organization. It organizes the data table into datasets.

Some of the benefits of BigQuery for the data warehouse practitioners are:

  • BigQuery allocates query and storage resources depending on the requirement and usage. Therefore, it doesn’t require the provisioning of resources before usage.
  • It can store data in different formats for efficient storage management. For example, Google’s distributed file system, proprietary format, proprietary columnar format, query access pattern, etc.
  • It is fully maintained and managed without any downtime or hindrance.
  • It provides backup and disaster recovery at a broader level. Users can easily undo changes and revert to a previous state without making a request for the backup recovery.

29. What do you know about Google Cloud SDK?

Google Cloud SDK (Software Development Kit) is a set of tools that are used in the management of applications and resources that are hosted on the Google Cloud Platform. It is comprised of the gcloud, gsutil, and bqcommand line tools.
Google Cloud SDK runs only on specific platforms like Windows, Linux, and macOS and requires Python 2.7.x. Other specific tools in the kit may have additional requirements as well.

30. What are the Google Cloud APIs? How can you access them?

Google Cloud APIs are programmatic interfaces  that allow users to add the power of everything (from storage access to the image analysis based on machine learning) to Google Cloud-based applications.

Accessing Google Cloud APIs

Cloud APIs can be easily accessed with the client libraries from the server applications. A number of programming languages can be used to access Google Cloud APIs. One can use mobile applications via Firebase SDKs or through third-party clients. Google Cloud Platform Console Web UI or Google SDK command-line tools can also be used to access the Google Cloud APIs.
